Correct me if I am wrong, and I could be since I was told this by a
flunkie at MicroCenter, but if you have the full version of XP you
should be allowed to install it on two different PCs. I was told that
the full version allows two installs. I was asking because I am going to
be building a new PC soon and I also have been wanting to upgrade my
existing PC to XP Pro. I was concerned that I would have to buy two
copies of XP which would be ridiculously expensive. I asked the
salesperson if you could buy one copy and then get two site licenses.
That's when they told me that you could install the full version on two
different PCs but no more. So is this true or not?
